WASH-BOILER TANK.

SPECIFICATION forming part of Letters Patent No. 400,425, dated April 2, 1889. Application filed June 10, 1886. Renewed November 28, 1887- Serial No. 256,365. (No model.)

, Tanks, of which the following is a specification. 7

My invention is a portable stand surmounted with a boiler-tank, which serves as a convenient vessel for washing clothes there- 1n by the aid of the ordinary wash-board or means for operating on them, and in which f vessel the wash-water is heated and kept hot by an oil-stove or other heater arranged there under. a

It consists more particularly of improvements in the construction of the tanks bottom, and to a jacket attached thereto beneath 1t, which communicates interiorly with the tank and forms fines between it and said bottom extending from a fire-confine lowerdown, 1nto which the heat of the stove is directed, as hereinafter more fully described, and pointed out by the claims.

In the drawings, Figure 1 is a longitudinal vertical section of my tank and stand with an oil-stove mounted thereon. Fig. 2 is a vertical cross-section of the tank; and Fig. 3 is a bottom View of the jacket, the lower marginal sheet being removed to disclose the waterways therein.

In the further description. the same letters by letter A and the water-level therein by X, its supports by a, which latter are battened together by the cross-pieces a. The hipped bottom E E of said vessel has the longitudinally dished or slant sections E, which latter are secured to the upper edges of'the ends A A Said vessel is denoted and the sections E and E are also extended up laterally and secured on top of the sides A The parts A A A compose a wooden frame, to which said metal parts are nailed at b and d in position, as shown. To the under side of said hipped bottom are riveted or soldered the flanged side pieces, V V, made to conform to the under side of said bottom and extended nearly from end to end thereof. Said side pieces are parallel to each other and are joined together by the transverse fire plates or sheets D. Said side pieces and fire-plates are made, preferably, of malleable iron in sectional castings. Said fire-plates are arranged parallel -to said bottom, and a little distance below it, excepting at their outer ends, which are bent up and joined to the sections E of said bottom, as shown. The inner ends of said plates D are turned downward, and they, in connection with the side fire-plates, D, compose the pendent fire confine or box D which serves to inclose and direct upward all the heat from an oil-stove, J ,or other heater, arranged below and part way inserted into said confine.

The side pieces, V V, are provided with the studs or lugs S in the walls at the corners of said fire-box D and the plates D D abut against saidstuds S, as shown in Fig. 3,thus causing the water-passages P P B to be formed between the plates D and the side pieces, V V, and between the plates D and the sheet-metal sections Z Z, respectively. The side pieces, V V, are provided at their lower edges with interior shoulders, on which are secured the lateral edges of said sheetmetal sections Z Z, which are made to conform to the fire-plates D, but are a little way apart from them, thus forming the water passages B, which latter are closed below, but

communicate with, the interior of the vessel A at the openings L L, and they also com municate with said passages -P P around the corners of the confine D Said water=pas= sages, with the platesD D, the sections Z Z,

into the vessel A at the openings L L, and a colder portion replaces the transferred hotter portion by flowing from said vessel A through the openings '2' into the passages P P. Said jacket-for brevitys sake denoted by the letter Qis provided with the discharge-tube N, having the pivoted gate M. The same is so located and adapted that the water in both the vessel A and in the jacket Q may be thoroughly discharged to clear them of sediment. The openings L, L, and 7' are provided with wire-gauze or other suitable strainers, to prevent small fabrics or pieces of clothing being floated into said jacket.

The oil-stove J, provided with the burners H and base K, is shown mounted upon a plat form, R, and the latter placed upon the crosspieces a, attached to the supports a at such elevation that the top of the stove is kept projected within the fire-box D I claim- 1. The combination of the vessel A, having the hipped bottom E E',and the pendent water-jacket Q, opening at different levels into vessel A, and comprising the side plates, V V, the fire-plates D D, forming the fiues, and the skirting-sections Z Z, substantially as and for the purposes set forth.

2. The combination of supporting-frame a a, "essel A, having hipped bottom E E, depending water-j acket Q, opening into the vessel A at different levels and forming the confine and fines, support R, and the heater projecting into the confine, substantially as and for the purposes herein shown and described.
